BCC = Bitmain Centralized Coin
Larger blocks mean more bandwidth and local storage needs. This means that regular users are less likely to participate in transaction verification, which leaves it to larger corporate interests.
This isn't a fork, its someone cloning BTC code and twiddling the knobs. Most economic actors have said they won't be supporting this change, so it looks like Bitmain and Jihan Wu will be standing by themselves.
If you trade this token for profit on the short term, I understand, but longer term I think it will have a very limited use-case.
